ABSTRACT:
Changing a mode of operation of a destination communication device by establishing a voice service option communication channel over a network between an initiating device and a destination device. Using the voice service option communication channel, a predetermined sequence of data is transmitted from the initiating device to the destination device. The predetermined sequence of data specifies a different operation mode of the destination device. The destination device receives the data packet and determines if it is a predetermined sequence of data. If the data packet is a predetermined sequence of data then the destination device examines the sequence of data and changes its operational mode in response to the predetermined sequence of data. The predetermined sequence of data may be transmitted in compliance with a TTY standard for data communication.
